Fractional deionization

QUA Group LLC’s FEDI stacks, which have superior hardness tolerance compared to the other electrodeionization products on the market, and a dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling and improving the plant’s design economics and reliability. FEDI stacks are available in three different models, which can be applied either for higher hardness tolerance or high water flowrates. http://www.environmental-expert.com, sales@quagroup.com
